IMPROVEMENT IN FOLDING-CHAIRS.

Specification forming part of Letters Patent No. 138,892, dated May 13, 1873; application filed April 22, 1873.

To all whom it may concern:

Be it known that I, GEORGE HUNZINGER, of the city and State of New York, have invented an Improvement in Folding-Chairs, of which the following is a specification:

This chair is made with cross or X legs hinged at the intersection, in combination with a bow connected to the upper ends of the cross-legs andformin g the back and arms. The bow is united by slots and pins in such a manner as to fold with the legs, and the bottom is made with a frame hinged near the front to one pair of legs, and resting, when in use, upon a cross-bar between the other pair of legs. This construction is cheap, strong, convenient, and folds easily into a small compass.

In the drawing, Figure 1 is a side View of the chair as folded. Fig. 2 is a vertical section of the chair as open for use, and Fig. 3 is a front elevation.

The legs a and b are united in pairs by the pivot-bolts or pins 0 at the points of intersection. The bow d forms the back and arms of the chair, and it is connected to the upper ends of the cross-legs a b and sustains them at the required distance apart when the chair is open, but allows the legs to fold, as in Fig. 1. This is accomplished by slots '6 and pins 0. The slot is shown in the upper ends of the legs a; but it might be in the arms or sides of the bow d. The joint I unites the upper ends of the legs I) to the how 01. There are cross-bars f and g to unite the pairs of legs a a and b 1) near their lower ends, and the scat h is united to the cross-bar k and swings thereon, and, when turned down into place, said seat rests upon the cross-bar a, between the legs b b. The back part of the chair may be inclosed by flexible material extending from the bow d to the cross-bar n. This back may be more or less upholstered or padded, and the seat may also be upholstered or stuffed or closed with elastic material, or caned.

I am aware that the arms of a chair have been hinged to the front of the X-legs, and, also, to the sides of the separatehinged back, and that a back with arms has been connected to the front legs in a chair that'is not provided with X-folding legs.

In my chair the bow forms both back and arms, and, being connected with both the X- legs, as set forth, allows of their folding.

I claim as my invention 1. The bow at connecting the top ends of the cross-legs a b and forming the back and arms of the chair, as set forth.

2. The flexible material extending from the back d to the cross-bar n, in combination with the seat h connected to the legs a a by the cross-bar k, and resting, when in use, on said cross-bar a, substantially as set forth.

Signed by me this 18th day of April, A. D. 1873.
